Coleoptile Senescence in Rice (Oryza sativa L.)

Correlation Studies in Rice (Oryza sativa L.)

Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...

Identification and Comparative Analysis of Premature Senescence Leaf Mutants in Rice (Oryza sativa L.)

Premature leaf senescence negatively impacts the grain yield in the important monocot rice (Oryza sativa L.); to understand the molecular mechanism we carried out a screen for mutants with premature senescence leaves in a mutant bank generated by ethyl methane sulfonate (EMS) mutagenesis of elite indica rice ZhongJian100. Five premature senescence leaf (psl15, psl50, psl89, psl117 and psl270) m...

Iron Bioavailability and Arsenic Uptake in Rice (Oryza sativa L.)

DIVERSITY ANALYSIS IN BORO RICE ( Oryza sativa L . ) ACCESSIONS

An experiment was conducted with 36 accessions of traditional (local) Boro rice germplasm accessions of three different groups (20 accessions as Kaliboro, 12 as Jagliboro and 4 as Tepiboro) during Boro season 2004 at BRRI farm to identify the duplicates with the help of morph-agronomic characters. On the basis of D values, the 36 genotypes were grouped into six clusters with a range of intra (0...

Genetic Diversity in Sadajira Rice (Oryza sativa L.) Germplasm

Genetic diversity of 40 traditional Bangladeshi rice genotypes was studied under rainfed condition through Mahalanobis D statistic for grain yield and yield contributing characters. The genotypes were grouped into six clusters. The inter-cluster distances were higher than intra-cluster distances indicating wider genetic diversity among the genotypes of different clusters. The intra-cluster dist...
